Title: Method for heating molten steel in tundish
Inventor: KOGA YOSHIO
IPC: B22D11/10
Filed: 2001-02-06
Abstract: PROBLEM TO BE SOLVED: To provide a method for heating molten steel in a tundish which can widen the adjusting allowance of an impressing electric power and is simpler than the conventional method and has a low operational cost. SOLUTION: In the method for heating the molten steel in the tundish with a twin-torch type plasma heating device in a heating chamber arranged in the tundish, oxygen concentration is controlled by measuring the oxygen concentration in the heating chamber and controlling argon flow rate blown into the heating chamber to control the impressing electric power for plasma. Particularly, the concentration of oxygen having the lower electric conductivity than argon, is raised by reducing the flow rate of the argon blown into the heating chamber under condition of fixing the current and a torch gap. Further, the impressing electric power can be increased by raising the voltage and thus, such two effects as the reduction of the argon cost and the increase of the impressing electric power, can be simultaneously obtained.
